European Standard Boiler Pressure Vessel Steel Plate

Raw Material Selection: High-quality alloy steel is chosen based on the specific requirements of the pressure vessel application. Common materials include carbon steel, low-alloy steel, and stainless steel.

Melting and Refining: The selected alloy is melted in electric arc furnaces or basic oxygen furnaces. Advanced refining techniques, such as vacuum degassing, are often employed to remove impurities and achieve the desired chemical composition.

Continuous Casting: The molten steel is cast into slabs using continuous casting machines. This process ensures uniform solidification and minimizes segregation of alloying elements.

Hot Rolling: The cast slabs are reheated and passed through a series of rolling mills to reduce thickness and achieve the desired plate dimensions. This process also helps refine the grain structure of the steel.

Heat Treatment: Depending on the material grade and required properties, the plates undergo various heat treatment processes such as normalizing, quenching, and tempering. These treatments optimize the microstructure and mechanical properties of the steel.

Surface Finishing: The plates are typically descaled and may undergo additional surface treatments to enhance corrosion resistance or prepare them for subsequent fabrication processes.

Cutting and Sizing: The plates are cut to the required dimensions using methods such as plasma cutting, water jet cutting, or mechanical shearing.
